below sea level
It is because you are going "below" sea level. It is like saying going below zero, since sea level is at zero elevation. If you were to go "below" zero, you would get a negative number, the same with going below sea level. Since you are going below 0 [elevation], you write your elevation below sea level in a negative value.

It can mean the height from the ground to the roof peak, or the ground elevation above or below sea level.
"Elevation" refers to the height of the land above or below sea-level. For example, mountains generally have a high elevation. Coastal regions generally have a low elevation.
A negative elevation usually refers to the distance below sea level of a point on dry land. For example the lowest dry land on earth is the shore of the Dead Sea in Israel at -418m; that is it has a negative elevation of 418m. Guns and canons also use elevation. Obviously if you are firing from above on a target below you will use negative elevation.
